I just charged my a/c and was wondering what everyone else is getting at the vent. Mine is reading 56 degrees. That is with a digital thermometer, With it on max full blast recirculating. at 2500 rpm

 

The temperature at the vents is a relative reading. You really need to get a few different readings to see if your vent temps are accurate and appropriate for conditions. When you charged up your A/C did you use a manifold system reading both high and low sides? Did you get ambient temperature in front of the condenser? The ambient temperature will affect air flow through the condenser and thus affect vent readings. Did you put your thermometer in the center vent or side vent? It should always be in the center vent. Finally them after getting those readings you can tell if your vents are reading correctly.

I checked mine last week and with an ambient temp between 90-100, low side at 43 and high at 225 my center vent was reading 55*F. If I revved the RPMs I could get it down to 52*F. See how it's all relative?

 

well I install home a/c and our service guy hooked up his gauges with some adapters. we put it on a vaccume for 30 mins. Micron gauge went below 500. the he put 2 pounds of 134a in it. checked his pressure and every thing looked great. thats all we did
